To all who ml it may concern:

Be it known that I, DOUGLAS TURNER, a citizen of the United States,residing in the city of St. Louis and Stateof Missouri, have 5 inventednew and useful Improvementsin Cloth Winding or Measuring Machines, ofwhich the following is a specification.

This invention relates to cloth-winding and cloth-measuring machines.The general -object of the invention is to provide means for windingcloth which will operate Without subjecting the cloth to high tensionand which is so constructed that in passing from the supply bolt to thenewly formed bolt or roll, the web of cloth will'pass as nearly aspossible in a direct line, that is to say, one of my objects is to avoidthe necessity of employing the usual guide rollers which carry the webin a circuitous path, thereby increasing the tension; in this Way'Iavoid placing the web under high tension, and

this increases the accuracy of measurements made of the length of theweb in winding the cloth. It has also beenan object of the inventiontoprovide means whereby the operator can examine the character of thetexture of the cloth in the pass-v ing web when desired. The inventionis very useful in winding doubled cloth, that is to say, a two-plyfabric having a creased edge, as it enables a new bolt tobe formed inwhich the unwinding direction ofv the new bolt is the same as the supplybolt with respect to the location of the creased edge. This is mostdesirable for-practical reasons. The machine is particularly useful. forchecking the lengths ofbolts of cloth when purchased from wholesalehouses, and alsov for measuring off predetermined quantities of cloth inbolts or rolls. One of the objects 0f the invention-is to construct themachine so as to enable it to handle fabrics of different widths. Withmachine's of'this type,ameasuring machine is frequently em-. ployed,which is driven by ameasuringroller provide automatic means for"stopping the One of theobjects of my 'lIlVGIl, tion is to prevent suchan inaccuracy, and to,, I I p p reel WhlQhl may employ;

. actuation of the measuring machine when the end of the web leaves itsface. Further objects of the invention are to provide an improvedorganization ofthe winding heads, and to improve their specificconstruction. It hasalso been the general ob]ect of my 1nvention toimprove the details of the general scribed in the followingspecification, while the broad scope of my invent-ionwill. be pointedout in the appended claims.

In carrying out my invention, I provide an under frame 1 whlch supportsthe ma chine at a convenient heightabove the floor,

and the oppositeendsof this frame are providedwith drop leaves 2 (Fig.9)'fwhich can be held up in a horizontal position 'so as to'operate asconvenient landing shelves or tables, useful in handling the bolts orrolls of cloth. The frame proper of the machine includestwo oppositelydisposed side frames 3 and 1, the latter of which supports most of themechanism of the'm'achine, (see Figs. 4: and 9). These side frames areconnected rigidly together by horizontal frame bars designatedgenerallyby the number 6. Y

The winding mechanism includes a receiving reel 7, (see Fig. 4), whichcomprises a winding head or receiving head 8 carried by the sideframe,and an adjustable receiving head 9 which is carried in the side frameThis receiving head 9 in axial alinernent with the (to-operating head-8,and ismade adj ustable, by attaching it to] a shaftor stem 10 mountedto slide through a bearing 11 attached'on the side frame 3.

On the opposite side of the machinethere is mounted a supply reel12which consists of a supply winding head 13 rotatably mounted'on theside frame 4:, and a winding head 14 a-lining with it an dfsiipportedjne ar the side frame 3. This Winding head 14 is adjustabletoward orfrom the head 13. For this purpose, it is mounted upon a shaftmounted rotatably in a long bearing 15 the support for whichwillbedescribedmore in detail hereinafter. 1" f I provide means fordriving the receiving heads 8 and 9 insynchrony with each other andmeans for driving the winding heads 13 'andl14 in synchrony with eachother. I

also provide differential means for driving the reels, that is to'say,the reel composed of the pair of heads 8 and 9 is driven differentiallywith the reel composed of the pair of heads 13 and 14. The effect of thedif ferential driving mechanism is to impart differential rotationtoboth reels, that is to say, I do not only drive the reel that the clothis winding upon, but I also drive the reel that the cloth is windingfrom. In this way I avoid subjecting the web of cloth to undesirabletension in passing between the reels, which stretches the cloth andcauses inaccuracy in measuring it. Furthermore, I provide aslip-connection in the drive to the supply reel, whichoperates in such away that if the supply bolt of cloth is mounted in' this reel in thewrong position,

thatis to say, in such a position that when it is rotated it will tendto wind up the cloth insteadof winding it oil"; then this slipconnection will slip and thereby avoid placthe wormwheel 18 loose on theshaft 19,v but rigid with a sprocket wheel 20, the sprocket chain 21 ofwhich drives a sprocket wheel 22 carried rigidly by thediiferentialshaft 23. The diii'erential shaft carries a spider 2 1 withradially disposed :pinions 25 which operateto drive two bevel gears 26and 27, the former ofwhich. carries rigidly a gear .wheel 28,meshinglwith ya geai' wheel 29 whichis attachedto a spindle or shaftQSlthat carries the atoresaid winding-head 8.

The bevel gearQT isrigid with, the sleeve 30,

'ca'rr in a bevel 'ear 31wvhich drives a bevel gear 32 carried a shaftincluding an outersect1on33? which is provided i with a bevel gear 34for driving abevel gear 36 carried on the end oft-heshaft or spindle 37of the aforesaid winding head 13. In this. way, the two winding heads 8and 13 are driven dififerentially.

I hall now describehow the winding.

head 8 drives its co-operating winding head -9 in synchrony with itself.

4), which drives a sprocket chain 39 passing over a sprocket wheel 40which is rigidly attached to the shaft 19, and the outer end of theshaft 19 carries a sprocket wheel 41 ing the head 13 in through themovement of which a sprocket chain 42 is driven. This chain 42 passes.

around a sprocket wheel 43 which is splined on the shaft 10 of theadjustable winding head 9. It should be understood that the diameters ofthe sprocket wheels 38, 40, 41 and 43 are such that the head 9 will bedriven at the same speed and in synchrony with the head 8.

I shall now describe the means for drivsynchrony with the head 14.

For this purpose, the spindle or shaft of the head 13 carries a sprocketwheel 44, over which passes a sprocket chain 45 which drives a sprocketwheel 46 on a shaft 47 extending between the frames 3 and 4, and

this shaft 47 carries a sprocket wheel 48 driving a sprocket chain 49which in turn drivesa sprocket wheel 50 connected with .the head 14.

The shaft 10 of the winding head 9 carries a knob 51 (see Fig. 3) whichenables the head to be adjusted in or out. i

I shall nowdescribe the means for adjusting the winding head 14toward orfrom its co-operating head 13, referring especially to Figure 3. Thebearing 15 is carried on a sliding frame 52 which is mounted to slide onone of the aforesaid horizontal guide rods 6 and 6.

so that it moves along with the sliding frame.

The shaft (Fig. 4) carries a slip-connection or slip drive for drivingthe supply reel 12. This slip-connection is preferably in the form of aclutch-56 including a conical clutch member 57 attached to a slidingcollar 58 which is pressed by coil-spring 59 so that it tends to holdthe clutch member 57 in engagement with the driven clutch member 60, thelatter clutch member being carried by the shaft 33 which carries thebevel gear 34 referred to above. The shaft 33 is provided with a tensiondevice which enables a suitable resistance to be offered in driving thesupply reel 12, the effect of which is that. the web of clothwillbesubjected to just the right amount of tension in winding it, off of thesupply reel 12. This tension device 61 is illustrated in Figure 4, butis shown in detail in Figure 19; it simply consists of a disk orbrake-wheel 62, carried on the shaft 33 and provided with a brake-band63, one end of which is fixedat 64 and the other end 68 of which has aslidable connection on a stem 65 the upper end of which pivotallycarries a camlever 66. This cam-lever has a projecting toe or cam 67.Evidently by rotating the cam-lever 66 toward the left, the toe: 67 canbe brought into contact with the end the band on the wheel 62. Figure 3slows how this brake-band 63 is attached to a fixed bracket 69,accessible through an opening 64, of the brake-band and thisWilltighten,

69 in a gear case 69". The stem 65 is provided with threads 70 at itslower end to receive a threaded adjusting sleeve 1 having a knurled head72 which can be rotated to adjust the tension of the brake-band 63. Acoil spring 72' is interposed between the end. of the sleeve 71 andbrake-band 68 in order to provide a yielding'pressure on the brake-bandand equalize the pressure exerted by the sleeve 71. This keeps thebrake-band from ever binding tight on the wheel 61.

Although "the slip-connection or clutch 56 does not necessarily includemeans for opening the clutch, l prefer to provide a lever 73 for thispurpose, which is pivoted at its inner end to a floating link 74andconnected'by ascrew' 75 to the side of a hub or collar 58 which'iscarriedby the movable .clutch member: 57. In order toenable the windingheads to be driven by hand when desired, the shaft of the motor l6carries a bevel gear. 76 (see Fig. 4;), -whic'h canbe driven by asimilar bevel gear 77 carried on V the end of a shaft 78 having. a handwheel 79 for rotating it at will. 1

Referring especially to Figure 9,; between the reels 7 and 12andirotatably supported in the side frames 3 and 4, I provide a meas llUuring roller 80, the upper face of which "is countersunk into a tab-1ewhich includes a fixed leaf 81 and an adjustable leaf 82. Thisadjustable leaf 82 is attached between two arms 83 (Fig. 2) which arepivotally attached on the axis of the trunnions of the measuring roller80. This table may be held in an elevated position as in Figure 9, or itmay be dropped down into an i'nclined position at whichtime it will besupported 109 thrusts.

in winding from one reel to the other. The direction of rotation of thereels is indicated in Figure 9.

lVhen the leaf 82 is held in its inclined position the are of contact ofthe cloth with the measuring roller is increased which tends to givegreateraccuracy in measurement.

The leaf 82 is provided with a cutting device 91 (see Figs. 3, 9, 13 and14) this cutter includes a semi-circular slide block 92 (see Fig. 13)which carries two guide plates 93 which extend down through a slot 94which extends longitudinally in the leaf 82 (see Fig. These guide plates93 are cut on their forward edges so as to provide a guide throat 95 forguiding the edge of the cloth into a position to be cut by the edge of aknife 96 which is clamped in an inclined position in the block. In orderto increase the rigidity of the table leaf 82 at the slot, I provide Ushaped brackets 97 for straddling theslot (see Figs. 9 and 14:). lVhenthe cloth is to be cut, one edge of the web may be'clamped on the faceof the leaf by means of a suitable clamping device 98 including twohorizontal clamping fingers 99 which hold the cloth against the table onopposite sides of the slot (see Fig. 3). These fingers are attached to adepressible head 100 (see Fig. 1) which is attached to the upper end ofa stem 101, and are normally held elevated by a coil-spring 102. Thestem 101' carries a laterally projecting handle 103 by means of whichthe clamping device may be operated.

I shall now describe the manner of driving the indicating mechanism of ameasuring machine 104, (see Fig.- 3). The indicating mechanism presentsnumbers on a dial 105, which indicate the length or amount of the webwhich has passed the measuring roller; and I shall also describe theautomatic means which I provide for stopping the movement of theindicating mechanism when the end of the web passes the measuringroller. This feature of the machine is very important, because if themeasuring roller spins or continues to rotate, after the end of the webleaves it, the measuring machine will indicate a greater length of cloththan was actually carried by the bolt.

Referring now especially to Figures 3, 17 and 18, the shaft or trunnion106 of the measuring roller 80 is mounted in a suitable ball-bearing 107beyond which the shaft is provided with a clutch 108 which is normallyheld closed by a coil-spring 109 thrusting against a fixed collar 110 onthe shaft 106; the clutch 108 includes a relatively fixed clutch member111 and a sliding clutch member 112 against which the spring Beyond theclutch member 111, the shaft 106 carries a loose bevel gear 113 whichmeshes with a driven bevel gear 114 carried on a shaft115 which extendsinto the interior of the measuring machine 104 in order'to drive theindicating mechanism. The clutch member 112 is splined on the shaft 106and is driven by the measuring roller 80 when it rotates. When theclutch member 112 is engaging the clutch member 111 the movement of themeasuring roller is imparted to the indicating mechanism.

I prefer to provide electrical means for opening this clutchautomatically when the end of the web leaves the measuring roller, inmeasuring the length of a bolt.

I shall now describe the means I employ for this purpose.

The measuring roller 80 is provided with a circumferential groove 116 (Fig. 18) in which lies an arcuate metallic contact strip 117 (Fig. 17)which is carried by a metallic tongue 118, connected to the conductor137 leading to the electromagnet 128 (see Fig. 18). Above the measuringroller there is mounted a presser roller120 which is also provided witha circumferential groove 121, similar to and opposite the groove 116,and

into this groove 12]. anarcuate metal con-.

tact 122 projects, the same being attached by a clip 123 to a metallicarm 124 which is disposed at one end of the presser roller. There aretwo of these arms 12 1' that support the presser roller between them andthey are pivotally mounted at 125, (seeFig. 1). I provide an electriccircuit 126 (see Figure 17*), which connects up these contacts 117 and122. These contacts are springs tending to come together, and when theyare in engagement with each other, the circuit is closed; however, whenthe machine is measuring cloth, the web 90 of the fabric is disposedbetween the contacts and holds them apart. The cont-rolling circuit 126ineludes an electromagnet 128 which is mounted near the upper side ofthemeasuring machine 104, and in a position to attract an armature 129attached to the upper end of a lever 130, which lever is pivoted at 131,(Fig. 18) the lower end of which is formed into a yoke 132 carrying pins133 which engage in the groove 134 in a collar formed on the movableclutch member 112. This circuit 126 includes a suitable source of E. M.F., such as a battery 135, and at a suitable point on the windingmachine a switch 136 is provided which should be closed when the machineis in operation. A

conductor 137 connects theelectro-inagnet with the contact 117, whileanother 'conductor 138 connects with the upper contact 122.

It is evident that as soon as the endof the web leaves the vicinity ofthe measuring roller, the contacts 117 and 122 will come together byreason of their resiliency,

and this will close the circuit and open the clutch 108, therebystopping the driving of the indicatingme'chanism. i

The arms 124 are connected by a transverse tubular rock shaft 139 (Fig.9) and are also covered by a rigid hood 140 which envelops them andextends over the presserroller. When it is desired to' raise the presserroller off the measuring roller, this is accomplished .by'means of alever 141 which is connected with the tubular rock shaft- 139.This/lever is provided with a hand-operated catch 142, the latch ofwhich can be engaged under a lug or shoulder 143 at an elevated point onthe frame (see Fig. 1) when in this position the presser-roller will beheld elevated above the measuring roller. I do not desire that thepresser roller should be pressed with great force against the measuringroller. In fact, I prefer that it should press very lightly upon themeasuring roller. However, in order to produce a slight and adjustablepressure, I provide a coil-spring 144 at each side of the machine, (seeFig. 9). These springs are anchored at 150. at their lower ends, andtheir upper ends are attached to adjustable screws:

151 received in suitable brackets 152.

I may employ this machine for'winding" cloth onto tubes. For thi reason,I provide with the machine, a special head of the type illustrated inFigure 15*. This head has a conical body 158 the small end of which isadapted to be received within the end of j the tube, and the side ofthis conicalhead web is being wound .on or off of the tube.

The driving heads which are illustrated on the machine, are, of course,removable and interchangeable so as to permit the heads such as a head153 to be employed on one or both reels, if desired. 7

In this connection, it should be understood that it is most advantageousto wra dehcate silks and similar goods 111 1'01 form about a tubeinstead of in a bolt because there is less tendency for the fabric tobecome creased.

A preferred form of the winding head for holding the supply bolt, isillustrated in Figures 5 and 6; each headconsists of oblong or ovalplate 155 carrying and guiding slides 156 and 157, each slideineluding arack 158. These racks respectively mesh upon opposite sides of a pinion159 disposed on the axis of rotationof the head.

The slides are provided respectively with knobs or handles 160 by meansof which the slides can be pulled out to a desired adjusted position.The pinion 159 is rigid with a small ratchet wheel 161 with which a pawl162 co-operates enabllng the p1n10n to be locked: against rotation inthe direction which would permit the; slides to move inwa'rdly. The pawl162 is held in mesh with theteeth of the ratchet by means of a smallspring 168. Each slide carries a plate or blade 164 disposed parallelwith the axis of rotation of the head, and these plates or blades lie inthe same plane with each other so that they are in the proper relationto be received in the ends of a bolt of cloth. In

this purpose, I prefer to taper the inner ends of the blades, that is tosay, I provide them with inclined side edges 166. This givesithe bladesa form which facilitatestheir being inserted in the end of a bolt.

I I provide another type of head somewhat slmllar tothis, but adapted tobe used for holding a board about which the cloth is to be wound. Thistype of head is illustrated ing with a central pinion 170. Rigid withthis p1n10n 170 I provide a small ratchet wheel 171, and a co-operatingpawl 172 whlch locks the slides against being pulled.

their slides the concave form is absent and a fiat. form at this pointgives increased resiliency. In holding the board its edges are held inthe concave portions of the holders or clips 174. 1

Instead of employing heads of the types described above, I may provide areel such as illustrated in Figure 12, which is supported at one endonly.

tionof the shaft of one of the winding heads. Each of these shafts has areduced neck 178 with a tapered key 179 near its root, and also carriesinternally a ball 180 which slightly projects through the side wallof'theneck, being forced outward by a spring 181 held in lace by a smallcountersunk screw 182.

he head 175, already described, is provided with a hub 183 having agroove 184 at one side, to receive the key 179 which insures that thereel will not slip on the shaft. And the hub 183 is also provided with asmall opening 185 which receives the ball 180' and in this way the balltends to preplane of the oval plate: 167 see Flg. 10). Where theseholders join This reel consists. of a head 175 to which a tubular bodyis atorder to facilitate the use of this head for Each slide carries aresilient end'of the shaft.

I shall now dcscribe the means which I provide for indicating thetexture of the fabric to the operator of the machine as the I clothpasses between the reels. For this pura as frosted glass.

pose I provide a source of illumination on the side of the web which isremote from the operators position, so that the operator may observe thelight through the fabric, and in this way may note the character ortexture of the cloth. In this way he may note any imperfections in thecloth.

In order to accomplish this result, I provide the fixed table leaf 81with a longitudinal slot or window 186 (Fig. 8) beneath which I-providea trough 187 carrying electric-lights 188. Flush with the upper surfaceof the table leaf Iprovide a plate 189 of translucent ortransparentmaterial such In this way the slot- 186 operates as a windowthrough which the light passes upwardly, enabling the texture of thefabric to be scrutinized as it passes.

I prefer to inclose the motor in a housing comprising two plates 190 and191 (see Fig. 9). This housing extends up from a point right under themeasuring roller and operates as a screen to prevent the oil from themachinery from being thrown up against the cloth.

The operation of the complete machine will now be briefly stated. 7

A bolt or roll of cloth is mounted on the supply reel 12, and the looseend of the fabric is pulled across the upper face of the guide roller88, and then over the top of the table and between the presser rollerandthe measuring roller this operation is continued until the edge of thecloth is in alinement with the cutting slot94 (Fig. 9). The indicatingmechanism is then turned back to zero and the presser roller is let downonto the face of the measuring roller. The end of the cloth is thenpulled across the guide roller 89 and wound around the receiving reel 7.The direction of rotation of the reels is indicated in Figure 9, andhence the web 90 of the cloth will come oif of the upper.

side of the supply reel and pass onto the under side of the receivingreel. This direction'of rotation is desirable for the reason explainedabove, namely, that in winding two-ply material having a creased edge,the roll or bolt which is being formed will have the same direction ofwrap as the supply bolt with respect to the creased edge.

This direction of rotation is also advantageous by reason of the factthat the upper sides of the reels move toward the table, for the reasonthat with this direction of rotation, the reels constantly holdthefabric down against the adjacent roller of the table and incidentallyenable the height of the roller abovethe reels, to be reduced. Thisreduces the head room necessary for the machine, and is a desirableimprovement.

If the cloth is to be wound upon a board, the boardis put in placebet-ween the holders 174:, (see Figs. 9 and 10). p

As the cloth passes over the table leaf 81, the operator of the machineobserves the quality of the cloth as revealed by the light passing ulpthroughthe window 186. t

In pul ing the Web 9( across the table, theweb passesbetween thecontactsv 117 and 122 and holds, the circuitll26 o en, which permits thespring 109, (see F igs 17 and 18) to hold the clutch 108 closed. Hence.as the Web ispulled pastthe measuring roller, the measuring rollerdrives the indicating mechanism of the measuring ma chine lQt, and thisdriving' rnovement occurs until the endof the web passes from betweenthe contacts. WVhen the winding machine is beingused to measure thelength of cloth:

of the motor circuit should be opened so that the motor stops a littleshort of the amount required and the machine is then advanced byrotating the hand wheel 79 to the exact measurement required.
